Have you seen Smashbox's newest blush called O-Glow? It is blush that is said to work with your own personal chemistry to have you naturally blushing all day.

Here is the description from Smashbox.com:
Experience instant chemistry as your complexion is transformed from so-so to oh-so-glowing! The first intuitive blush, this clear gel reacts with your personal skin chemistry to turn cheeks the exact color you blush, naturally in just seconds! O-GLOW works on every skin tone, from the lightest to the darkest, to give everyone a naturally gorgeous glow. When applied, your skin's moisture activates the energizing Goji Berry-C Complex™. It creates a microcirculatory effect, producing a rosy flush that lasts all day. This revolutionary silicone-based clear gel works on every skin tone and is microcirculating and skin energizing to keep cheeks naturally flushed for hours. O-GLOW's unique Goji Berry-C Complex™ formula is full of antioxidants like vitamin C, pomegranate seed oil and marine plankton for added healthy-skin benefits. The completely natural looking, preservative and fragrance-free formula glides on smoothly for a healthy, glowing blush that's you, only prettier.

I don't know about you, but I am concerned. Can this really be good for your blood or your skin? Is this Goji Berry-C Complex a safe ingredient? I know that when I blush, my cheeks feel very warm. I mean, isn't blushing a surge of blood to your cheeks, or other areas? I am afraid to try this.

Has anyone used O-GLow yet? If you have, I am anxious to know - how did it feel? Did you cheeks feel warm? Did it last longer than a conventional makeup product?
